Yes, it's a recap movie.
Yes, it's a cash grab.
However they did change the ending scene, which is what I wanted to discuss.
I've put the scene in webm format for your convenience
So the original ending had C2 lying in the back of a horse drawn cart talking to an "unknown man".
They've now change that so there is no cart or man just her on a horse reading a letter.
However the scene still has the cart wheel marks in the mud?
How does this affect the setup for the next series compared to the original ending?
I think it's worse.
